<span class='line'>  5</span>  * Graph3d is an interactive google visualization chart to draw data in a
<span class='line'>  6</span>  * three dimensional graph. You can freely move and zoom in the graph by
<span class='line'>  7</span>  * dragging and scrolling in the window. Graph3d also supports animation.
<span class='line'>  8</span>  *
<span class='line'>  9</span>  * Graph3d is part of the CHAP Links library.
<span class='line'> 10</span>  *
<span class='line'> 11</span>  * Graph3d is tested on Firefox 3.6, Safari 5.0, Chrome 6.0, Opera 10.6, and
